各位老師，我想問(wèn)一下，我現在有個(gè)小項目

一個(gè)產(chǎn)品測量它的拉力或者說(shuō)是插拔力，我如何去測量

用什么儀器可以做到,我需要用到PLC判定它的壓力大小來(lái)確定它的好壞，

也就是說(shuō)必須有信號給PLC。無(wú)論是開(kāi)關(guān)信號還是電壓信號

請各位老師，大神們給點(diǎn)意見(jiàn)。
工控人加油

你這個(gè)產(chǎn)品是什么產(chǎn)品？棉線(xiàn)還是鐵線(xiàn)？棉線(xiàn)只有張力了。用個(gè)重坨拉個(gè)檢測元件。鐵線(xiàn)的張力和推力靠軋制電流來(lái)計算的。比較tu復雜。
